Detailed Description

The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

The method aims at the technical problems that in the prior art, after the answering part is completely put in the video playing, the learning efficiency of knowledge points in the video is influenced, and the learning cost is increased. The embodiment provides a method for processing a teaching video, which can be applied to a client side as shown in fig. 1, and the method includes:

101. and the client receives the video answering node sent by the server.

The video answering node can be regarded as a preset node for triggering answering in the video playing process. The number of the video answer nodes corresponding to each teaching video can be one or more, and can be determined according to the number of knowledge points needing to be enhanced in the video, teaching requirements and the like.

The video in this embodiment can be acquired from the server side, and the server side configures a corresponding video answering node in advance according to the video content of the video. For example, at each knowledge key node of a video, a corresponding video answer node is configured so as to add a corresponding test question, so that a user can do consolidation exercise at the first time when the knowledge is memorized, and the purpose of enhancing the video learning effect is achieved. Or when a specific noun appears for the second time in the video (for example, the meaning of the specific noun is already explained when the specific noun appears for the first time), configuring the corresponding video answer node to add the corresponding test question, so as to facilitate the understanding and the awareness of the user on the noun, and the like.

It should be noted that, in addition to being acquired from the server side, the teaching video in this embodiment may also be obtained from local loading, or obtained from downloading from a third-party platform, and the like. When the video answer node is obtained by local loading or downloaded from a third-party platform, the relevant information (such as a video identifier, a video download address, video content and the like) of the video can be sent to the server, so that the server configures the corresponding video answer node according to the relevant information of the video.

For example, when a video starts to be played, the client may request a video answer node corresponding to the teaching video from the server as a preset node for triggering answer. Or when the client requests the video from the server, the server issues the video answer nodes corresponding to the video as video configuration information together when issuing the video data, so that the video configuration information is read when the client plays the teaching video, and the video answer nodes and the like are obtained.

The execution subject of the embodiment may be a client for teaching video processing, such as a specific Application (APP) installed on a terminal of a smart phone, a tablet computer, a personal computer, or the like, or a module unit in a video APP. The teaching video in this embodiment may be a video that only records knowledge explanation content or a video in other content forms, and the client triggers corresponding answers according to at least one corresponding preset node in the process of playing the video.

102. And acquiring playing information in the teaching video playing process.

The playing information may include audio information, video frame information, and a time node corresponding to the current playing progress of the teaching video currently being played during the playing process.

103. And judging whether the current video answer node is reached according to the acquired playing information.

To this embodiment, whether the preset node of the triggered answer is reached currently can be judged according to the playing information in the teaching video playing process in the video playing process, and then the process of intelligently responding to the answer is achieved according to the currently playing content of the teaching video, so that the time for triggering the answer is more accurate, and the requirement for more accurate answer training is met. And cater to the content of the video, adopt more suitable opportunity to pop out the answer process, can improve the quick timely response of answer to reduce the inconsistent answer experience in the teaching video broadcast process, consequently can give the learner more have coherent video learning experience, can promote user's teaching video and watch the impression.

104. And if the current video answer node is judged to be reached, acquiring the information to be answered corresponding to the video answer node and outputting the information.

Wherein, different video answering nodes have the corresponding information of the question to be answered. The question information to be answered may include questions, options (e.g., choice questions), requirements (e.g., repeating a certain knowledge point content, repeating a certain word pronunciation), etc., related to the content of the knowledge point that has been played before the corresponding question answering node. The answering information corresponding to each answering node can be completely different or partially identical. The information to be answered can be obtained from the server side, or can be obtained by local reading (for example, when the server side issues video data, the information to be answered corresponding to the video answering node is issued together and cached locally as video configuration information, and then the information to be answered corresponding to the answering node can be read from the video configuration information).

The embodiment is equivalent to inserting an event for answering a question in a mode of triggering a node preset in advance in the playing process of a video. Compared with the prior art, the video answering node sent by the server side can be received at the client side for playing the video and serves as the preset node for triggering answering. Therefore, whether the preset nodes are reached currently can be judged according to the playing information in the teaching video playing process in the video playing process, and then the intelligent answer responding process is achieved according to the current playing content of the teaching video, so that the trigger answer opportunity is more accurate. When a preset node is reached, the information of the to-be-answered question corresponding to the node can be acquired and output, so that the user can answer the corresponding knowledge point of each node for multiple times in a segmented mode in the process of watching the video, the user can effectively master each knowledge point in the video, the situation that the user watches the learning repeatedly is reduced, the learning efficiency of the knowledge points in the video can be improved, and the learning cost is saved. In addition, by planning the video answering nodes through the background server, the targeted optimal answering node setting can be achieved according to the content characteristics of each video and/or the specific service teaching requirements and the like, so that the answering nodes are more reasonable, the memory of the user on the learning content can be better consolidated, and the video teaching effect is further improved.

Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully illustrate the implementation process of the embodiment, another teaching video processing method is provided, as shown in fig. 2, and the method includes:

201. and the client receives the video answering node sent by the server.

In this embodiment, the video answering node sent by the server can be received before the teaching video is played, so that answering can be triggered in time in the video playing process. In addition, the video answering nodes sent by the server can be received in the teaching video playing process so as to meet the real-time answering requirements (for example, temporary answering in the video live broadcasting process, real-time updating of the answering nodes and the like can all receive the latest answering nodes in the video playing process, so that the corresponding answering process can be triggered in real time/regularly afterwards).

202. And acquiring playing information in the teaching video playing process, and judging whether the current video answer node is reached according to the acquired playing information.

In this embodiment, there may be multiple optional manners for determining whether the current mode of reaching the video answer node exists, which may be specifically determined according to the service requirement. As an optional manner, the process of determining whether the current video answer node is reached may specifically include: acquiring currently played audio information according to the currently played information; then judging whether the obtained audio information is matched with the preset audio information of the corresponding trigger answer of the video answer node; and if the audio information is matched with the preset audio information, judging that the current video answer node is reached. The preset audio information can be obtained when the video answering node is received, namely a judgment condition for the answering process of the node is triggered. By the mode of judging the answering triggering condition through audio identification, the intelligent answering process can be achieved according to the current playing content of the teaching video, and the answering triggering time is more accurate. The quick and timely response of answering can be improved, and inconsistent answering experience in the teaching video playing process can be reduced.

For example, the determining whether the audio information matches with the preset audio information of the video answering node corresponding to the trigger answer may specifically include: and comparing the audio information with the preset audio information by audio characteristics, wherein the audio characteristics at least comprise: one or more of voiceprint characteristics, audio content, audio duration; and if the similarity between the audio information and the audio characteristics of the preset audio information is greater than a preset threshold value, judging that the audio information is matched with the preset audio information.

For example, whether a sound source in the audio is a sound source for triggering a question answer can be determined through voiceprint recognition (for example, whether a person who currently presents a question is a specific person who triggers the node to pop up a question answer, and the question answer can be triggered only by the audio content spoken by a specific teacher person who is responsible for the video teaching). Through the audio content recognition, whether the text content corresponding to the audio is the specific text content of the specified trigger answer can be judged (for example, the audio text content of the specified trigger answer is 'everybody reads Hello, Teddy', when the audio text content appears, a learner is guided to speak the pronunciation of 'Hello, Teddy' according to the preset answer node requirement, namely after a teacher teaches the pronunciation of English 'Hello Teddy', the learner is guided to speak the pronunciation of 'Hello Teddy' in the video). Through the audio frequency time length identification, whether the audio frequency time length corresponding to the audio frequency meets the time length requirement of the preset question answering time (if the audio frequency time length of the general question answering narration needs to be met) or not can be judged. In addition to these identification judgments, it is also possible to judge whether the current question is a question sentence, contains a long tone, or the like, based on the audio content, so as to judge more accurately and comprehensively whether the node that answers has arrived.

Through the optional mode, whether the current video answer node is reached or not can be accurately judged from the angle of audio identification, an intelligent answer response process can be realized, the quick and timely response of answer is improved, and the learner can be given more coherent video learning experience.

In addition to the above manner of triggering the answer opportunity by audio recognition, as another optional manner, the process of determining whether the current video answer node is reached may specifically include: acquiring the currently played video content information according to the playing information; then judging whether the video content information is matched with preset video content information of a corresponding trigger answer of the video answer node; and if the video content information is judged to be matched with the preset video content information, judging that the current video answer node is reached. The preset video content information can be obtained when the video answer node is received, namely, another judgment condition of the node to the answer process is triggered. By the mode of judging the answering triggering condition through video identification, the intelligent answering process can be achieved according to the current playing content of the teaching video, and the answering triggering time is more accurate. The quick and timely response of answering can be improved, and inconsistent answering experience in the teaching video playing process can be reduced.

For example, the determining whether the video content information matches with preset video content information of the video answering node corresponding to the triggered answer may specifically include: judging whether the image similarity between the currently played video frame content and the preset video frame content triggering answer is greater than a preset threshold value or not; and/or judging whether preset style content for triggering answer exists in the currently played video frame content, wherein the preset style content at least comprises one or more of a preset character style, a preset picture style and a preset gesture style; and if the similarity between the currently played video frame content and the preset video frame content is greater than a preset threshold value and/or preset style content triggering answer exists in the currently played video frame content, judging that the video content information is matched with the preset video content information.

For example, the content of a video frame at a time point before answering (e.g., the content of a video frame when a teacher takes a fruit and asks for which fruit is) is preset, and then the image similarity between the current content of the video frame and the preset content of the video frame is determined by means of image comparison, and if the similarity is greater than a certain threshold (e.g., 99.5%), it can be considered that the node triggering answering has been reached currently. In addition, whether the video frame content contains a preset character pattern (such as an applet character pattern), a preset picture pattern (such as an apple picture pattern) and a preset gesture pattern (such as a specific gesture in question inquiry or a specific gesture for guiding pronunciation and the like) can be judged, and whether the current video answer node is reached can be accurately judged through the optional mode, so that an intelligent answer response process can be realized, the quick and timely response of answer is improved, and the video learning experience with continuity can be provided for learners.

In addition to the two options of audio recognition and video recognition, as another option, the video answer node may be configured according to a time node when the content of at least one knowledge point in the teaching video is played. Correspondingly, the process of judging whether the current video answer node is reached specifically may include: and judging whether the current video answer node is reached according to the time node corresponding to the current playing content.

For example, in the video playing process, the current playing time node is monitored in real time, and if the current playing time node is matched with a preset time node, the information to be answered corresponding to the preset node is acquired at the moment, and the acquired information to be answered is output. When the information of the question to be answered is output, a mode of partially or completely shielding the video picture can be selected, so that the user can know the current answering link in time. Through the optional mode, the relevant answer is triggered immediately after the content of each knowledge point is played, and the video and answer insertion and combination mode can be used for immediately practicing and consolidating all knowledge points in the teaching video, so that the aims of immediately learning and practicing, pertinently consolidating memory and strengthening the video teaching effect are fulfilled.

For another example, after the content of a plurality of knowledge points related in a chapter is played, and before the next chapter of knowledge point is played, a corresponding video answer node is inserted as a preset node. Therefore, comprehensive answering is carried out according to the content of the current chapter, the memory of the related knowledge points of the content of the current chapter is consolidated, and the problem that the user experience is reduced due to frequent answering of each knowledge point when the number of knowledge points is too large is avoided. It should be noted that besides being divided according to chapters, a plurality of knowledge points in the video can be grouped according to the relevance of the knowledge points, the learning progress made at each time interval, and the like, and then the video answering nodes are configured according to the grouping result, so as to meet more personalized learning requirements.

It should be noted that the three optional modes can be combined and collocated according to actual service requirements, so that the opportunity of triggering answering can be comprehensively judged, and the quick and timely response of answering is improved. The intelligent answer responding process is achieved according to the current playing content of the teaching video, so that the answer triggering time is more accurate, and the more accurate answer training requirement is met.

203. And if the current video answer node is judged to be reached, the client sends an acquisition request of the information to be answered to the server.

The obtaining request carries a node identifier corresponding to the video answer node that responded (i.e., the currently arrived answer node). Namely, the video answer node identifier corresponding to the preset node currently reached in the video playing process. For this embodiment, the information to be answered corresponding to each preset node can be acquired from the background server, and the information to be answered can be obtained by the server through pre-configuration, that is, for the target video, the information to be answered corresponding to each preset node is fixed in advance, so as to implement quick response and issue of the information to be answered; or the information to be answered can be obtained by the server through dynamic configuration according to actual service requirements, for example, the background server dynamically selects a proper preset answering template and selects proper preset question content information to issue to the client according to individual answering preference of the user, and/or the answering condition before the user, and/or real-time video teaching requirements and the like, so as to meet more requirements and realize more targeted triggered answering.

204. And the client receives the preset answer template and the preset question content information which are returned by the server and correspond to the node identification, and the preset answer template and the preset question content information serve as the information to be answered corresponding to the responded preset node.

After receiving the preset answer template and the preset question content information, the process shown in step 205 may be executed, where the information to be answered corresponding to the responded preset node is output according to the received preset answer template and preset question content information.

205. And displaying the received preset answer template, and displaying the received preset question content information in the preset answer template.

The specific display form may have a variety of alternatives, and for example, step 205 may specifically include: and displaying the received preset answer template by using the answer mask or the answer interface, and displaying the received preset question content information in the preset answer template. The selection and use can be specifically carried out according to video content, personalized answer preference of the user and the like.

For example, the subject content to be answered is displayed in front of the video screen in a mask manner, and after the answer is completed, the mask disappears, and the video continues to be played. Or displaying a new complete answer interface, answering the questions in the new interface, returning to the video picture after the answer is finished, continuously playing the video and the like.

Because the content played by the video is partially or completely blocked during answering, and for the purpose of more attentive answering of the user and not missing other knowledge point content in the subsequent video, further optional, this embodiment may further include: pausing the playing of the video during answering; and continuing to play the video after the answer is finished (such as the answer is all matched, or the answer is finished and a correct result is displayed, or the answer time specified by the answer is finished). For example, the teaching video itself is preferably a content specially recorded for adding a question answering event, after the teacher teaches a piece of knowledge content, the teacher can be guided to answer the question in the video by dictating the question, at this time, the effect of pausing the video display question to allow the learner to answer is optimal, and the teaching video is played after the answer is finished.

In addition, in order to better guide the user to answer, optionally, the client outputs the acquired information of the question to be answered, and specifically, the method may further include: and outputting prompt information for prompting answering. Such as audio, video (picture in picture), picture, text, light, vibration, etc., for prompting the user to enter the answering stage. Through the optional mode, the user can be helped to better transit from watching the video to the answering process, and the use experience of the user is improved.

For example, the outputting, by the client, the prompt information for prompting to answer the question may specifically include: and outputting the audio information of the question content corresponding to the question to be answered. For example, for an off-the-shelf teaching video, after the teacher teaches a piece of knowledge content, directly displaying the question in this case gives the learner a disjointed video learning experience because the teacher within the video does not dictate the question to direct the answer. At the moment, a section of topic content is played at the same time when a question is displayed, so that the video learning fluency of the learner is enhanced.

In order to better and conveniently understand the answer style of the method of the present embodiment, the following three video interactive answer styles (examples shown in fig. 3 to fig. 5) are given for explanation, it should be noted that the present embodiment is given by way of example only, and is not limited at all, and the display style in the actual process may have more answer styles.

For example, as shown in fig. 3, after the teacher teaches the pronunciation of "HelloTeddy" in english, the learner is guided to speak the pronunciation of "HelloTeddy" in the video; at the moment, video playing is paused, an answer mask is displayed below the video, and a learner is prompted to pronounce and answer the questions posed by the teacher in the video; and after the learner finishes answering the questions by replying the pronunciations, the answer of the time is finished, and the video is continuously played.

For another example, as shown in FIG. 4, the teacher teaches the apple's English word "applet" within the video and guides the user in the video to select which answer is "applet"; at the moment, video playing is paused, an answer mask is displayed below the video, and a learner is prompted to click and select a picture option corresponding to the 'applet'; after the learner selects the correct answer, the answer is completed, and the video continues to be played.

For another example, as shown in fig. 5, after the teacher teaches the english words of 3 animals in the video, the learner is guided to connect the 3 words and the corresponding animals together in a line; at the moment, video playing is paused, and meanwhile, a complete answer display interface is switched to, so that a learner is prompted to answer online; and after the learner completes the connection of the corresponding options, the answer is completed, and meanwhile, the video is switched back to continue playing.

206. And receiving an answering instruction corresponding to the information of the question to be answered.

In the answering process, the client can receive an answering instruction input by a user, such as selecting a certain option, connecting a line, inputting a piece of audio, inputting a piece of text, clicking a certain picture, knocking and/or shaking a specific position of a screen, and the like.

207. And outputting answer result information according to the answer information in the answer instruction.

Specifically, the answering information can be compared with the correct answer to obtain and output the answering result information.

Further, in order to further deepen the memory of learning the knowledge points, optionally, if the answer error is determined according to the answer result information, the method of this embodiment may further include: and replaying the knowledge point video clip corresponding to the responded preset node. For example, the information of the to-be-answered question corresponding to the preset node is set for the content of the knowledge point in the video corresponding to the node, when the answer is judged to be wrong, the playing progress point can be advanced to the starting time point of the video clip corresponding to the knowledge point, and then the video clip of the knowledge point is played again, so that the user can know the reason of the answer mistake, and the understanding and memory of the wrong question are deepened. Further, if the answer has a plurality of questions and the answer is wrong for the time, only a part of the questions is answered, in order to improve the precision, the start time point and the end time point of the corresponding knowledge point video segment can be found according to the identification of the wrong question (for example, a corresponding mapping relation is established in advance, the start time point and the end time point of the knowledge point video segment corresponding to each question are provided by each question), then the video content of the knowledge point is replayed according to the found information, and the playing node is skipped to when the answer is answered after the replaying is finished. By the mode, repeated watching of the answer knowledge point video is avoided, the learning efficiency is improved, and the learning cost is reduced.

The method aims to solve the problems that a learner difficultly generates firm memory by simply watching a video at present, and the learner has knowledge forgetting to return to watch the video for learning after intensively performing answer training after a video class. According to the processing method of the other teaching video, the video and the answer are combined in a penetrating and inserting mode, real-time exercise and consolidation can be conducted on all knowledge points in the teaching video, the purposes of learning and practicing immediately and consolidating memory pertinently are achieved, and the video teaching effect is strengthened.

The content of the foregoing embodiment is a processing procedure of a teaching video described at a client side, and further, to fully illustrate an implementation of this embodiment, this embodiment further provides another processing method of a teaching video, which is applicable to a service side to illustrate a corresponding processing procedure at the service side, as shown in fig. 6, the method includes:

301. and the server configures video answering nodes.

The server side can configure corresponding video answering nodes according to the video content of the target video. The mode of configuring the video answering node can be determined according to actual requirements. As an exemplary option, step 301 may specifically include: configuring video answering nodes according to preset audio information for triggering answering; and/or configuring video answering nodes according to preset video content information of the triggered answering; and/or configuring a video answering node according to a time node when the content of at least one knowledge point in the teaching video is played. Corresponding to the three optional implementation processes in step 202, the opportunity for triggering answering can be comprehensively determined, and the quick and timely response of answering is improved. The intelligent answer responding process is achieved according to the current playing content of the teaching video, so that the answer triggering time is more accurate, and the more accurate answer training requirement is met.

In the prior art, if a teacher directly records a problem in a video in a manner of dictating in the video, the teacher only performs virtual interaction with a learner in the video. Not only needs to re-edit the video itself and increases a certain editing cost, but also needs the teacher to reserve a certain answering time in advance in the video recording process (for example, after the teacher inquires a certain question, the teacher needs to deliberately delay a period of time for the user to answer the question in the period), thereby invisibly increasing the difficulty of completing the teaching task of the teacher and prolonging the recording time of the whole video. Meanwhile, the mode of only recording the questions in the video cannot ensure that the learner can certainly complete corresponding answering actions along with instructions of the teacher in the video. And because the degree of knowledge accumulation of each learner is different, the learner can not be ensured to complete the answer to the question within the time reserved by the teacher in the video.

In this optional embodiment, the server may configure the video answering node in advance according to the time node when the content of the at least one knowledge point in the video is played, and then send the video answering node to the client as a preset node for triggering answering. In the process of playing the video at the client side, when the playing reaches a preset node, the information of the to-be-answered question corresponding to the preset node can be triggered and output, for example, relevant answering is triggered immediately after the content playing of each knowledge point is finished, or relevant answering is triggered in time after the content playing of each knowledge point is finished, and the like. The process does not need to re-edit the video, and the teacher can optionally reserve the answering time (for example, the video playing is suspended during answering) in the video recording process, so that the teaching task completion difficulty of the teacher is reduced, and the recording time of the whole video is not influenced additionally. Meanwhile, the method of the embodiment can ensure that the learner can certainly complete the corresponding answering action by following the instruction of the teacher in the video, and the learner indirectly reserves enough time to complete the answering of the question (for example, playing the video after answering is completed).

In addition to the above manner of configuring the video answer node, in order to meet the personalized answer requirement of the user, optionally, step 301 may further include: firstly, acquiring user characteristic information of a client login user; and then configuring personalized video answering nodes according to the acquired user characteristic information.

The user feature information may include user portrait data such as age, occupation, gender, color/style preference, comprehension ability, reaction ability, etc. of the user, may also include user correct rate, wrong condition, answering time, etc. for the past answering in the video, and may also include user correct rate, wrong condition, answering time, etc. for the historical video (for example, a video of the same or similar type to the content of the video). And the server configures a video answering node more suitable for the user according to the user characteristic information.

For example, the teaching video is a video of a child's english teaching, and the users watching the video are kindergarten children aged 4-6. The comprehension ability is weak, and the basic knowledge needs to be strengthened and consolidated, so that corresponding answer nodes can be configured at English pronunciation practice nodes to enhance corresponding English pronunciation practice, for example, a teacher guides English pronunciation of the word 'apple', and subsequent kindergarten children can pronounce corresponding words to realize the answer process; and corresponding answer nodes can be configured on the physical understanding of the English words, for example, corresponding answer nodes are added when the English word apple 'appears in the video, and fruit pictures such as apples, bananas, pears and the like are included during answering, so that children in a kindergarten can select physical pictures corresponding to the apple' during answering, and further the English word 'apple' is deeply understood. In addition, can also insert the answer link that corresponds when a certain doll appears, if when the Teddy bear doll appears, can provide several english name options, and then kindergarten children can select this name word of "Teddy" and accomplish the answer to can strengthen the memory understanding to english name class word, also can mobilize kindergarten children watch enthusiasm, promote the teaching video and watch experience.

For another example, the user watching the video is a 25-year-old office female, and has strong comprehension ability and reaction ability; the answer of the past video of the video can be quickly finished, and the accuracy is greater than a preset threshold value; and the user can accurately complete the relevant answer for the history video of the same subject, so that the memory of the user is strong, the video answer nodes can be set more widely, for example, corresponding answer nodes are set after the video content of the knowledge points of several chapters is played, and then the comprehensive answer is carried out aiming at the relevant knowledge points of the chapters, so that the frequency of frequently answering the question can be reduced, and the memory understanding of the user on the knowledge points in the video can not be influenced.

For another example, the retired aged 65 years old people who watch the video are weak in comprehension ability and reaction ability; the answer of the past video of the video is finished in a long time, and the accuracy is smaller than a preset threshold value; and the historical video answer situation of the same subject is not good enough, so that the memory of the user is poor, the video answer nodes can be set more densely, for example, a corresponding answer node is set after the video content of each knowledge point is played, and then the answer exercise is developed after the content of each knowledge point is explained, and the memory understanding of the people group to the knowledge points in the video can be increased by the method.

For another example, according to the answering scene of the same user in the same video, the default is that the answering training is performed at 4 knowledge points at intervals, if the memory comprehension capability of the user is determined to be poor according to the condition that the user answers the questions in advance, the subsequent preset nodes can be set more densely, and the answering training is performed at 1 or 2 knowledge points at intervals to strengthen the comprehension memory of the user.

Besides configuring the video answering node, the server can also configure a preset answering template and preset question content information corresponding to the video answering node identification so as to be used as the to-be-answered information of the preset node corresponding to the video answering node. In order to meet different requirements, each answer node can correspond to a plurality of selectable preset answer templates and corresponding preset question content information. When each user watches the same video, the same or different types of answer contents can be displayed on the same preset node, so that the personalized answer training requirement is met. For example, user characteristic information of a client login user can be acquired; and then configuring a personalized preset answer template and preset question content information corresponding to the video answer node identification according to the acquired user characteristic information.

For example, if it is determined that the user 1 prefers red relatively and has relatively poor memory according to the user characteristics of the user 1, a preset answer template with a red background can be made, and the question content can be in the form of a choice question (giving an option); if it is determined that the user 2 prefers blue according to the user characteristics of the user 2 and the memory is relatively good, a preset answer template with a blue background can be made, and the question content can be in the form of a short answer (no option given), and the like.

For another example, according to the user characteristics of the user 3, the user 3 is determined to be a pupil, and when learning a node of a word a in english, a pronunciation practice template and a pronunciation practice question for learning the word a can be set; according to the user characteristics of the user 4, the user 4 is determined to be a junior student, and when learning a node of a word a in English, a reading understanding template and a reading understanding problem related to the word a can be set.

302. And the server sends the video answering node to the client.

Wherein, different preset nodes have respective corresponding information of the questions to be answered. In this embodiment, the background server may dynamically configure and adjust the trigger time point of the question and answer of each video, the style template of the answer, and the content resource of the question, and further may consider the actual playing scene and the real-time teaching task change, and achieve the timely and accurate adjustment.

Correspondingly, in order to satisfy the requirement of timely updating the answer triggering time point of the video, optionally, the method of this embodiment may further include: the server updates the configured video answering nodes; and then sending the updated video answer node to the client so as to replace the previously sent video answer node. For example, updating the configured video answer node may specifically include: receiving answer result information sent by a client; and then updating the configured video answer nodes according to the answer result information. Besides timely adjusting the video answering nodes according to the real-time answering situation, the video answering nodes can also be automatically adjusted and updated adaptively according to a plurality of factors such as temporary change of teaching tasks (for example, the content of knowledge points needing to be strengthened changes).

For example, the configured video answer nodes of video 1 are to perform an insertion answer link after the 5 th, 10 th and 20 th knowledge on-demand playback ends, update the video answer nodes to perform an insertion answer link after the 2 nd, 7 th, 10 th, 15 th, 18 th, 19 th and 20 th knowledge on-demand playback ends according to the real-time answer situation of the user and/or according to the temporary change of the teaching task, and send the updated video answer nodes to the client to replace the previously sent video answer nodes. At this time, if the video 1 is played to the 6 th knowledge point, the answering training is subsequently performed after the playing of 7, 10, 15, 18, 19 and 20 knowledge points is finished, respectively.

303. And the server receives an acquisition request of the to-be-answered question information sent by the client.

The obtaining request is sent when the client judges that the current video answer node is reached according to playing information in the teaching video playing process. The detailed process can refer to the contents shown in steps 202 to 203, and will not be described herein.

304. And sending the information of the to-be-answered questions corresponding to the video answering nodes to the client.

The server receives an acquisition request of the to-be-answered question information sent by the client, wherein the acquisition request carries a video answering node identification corresponding to a preset node responded by the client; and then sending the preset answer template and the preset question content information corresponding to the video answer node identification to the client.

Referring to the above dynamic adjustment process of the video answer node, in this embodiment, the preset answer template and the preset question content information may also be updated according to actual requirements, and correspondingly, if the preset answer template and/or the preset question content information corresponding to the video answer node identifier is updated, the preset answer template and the preset question content information corresponding to the video answer node identifier are sent to the client, which may specifically include: and sending the latest preset answer template and preset question content information corresponding to the video answer node identification to the client. For example, the preset answer template and/or the preset question content information corresponding to the video answer node identifier is updated according to the answer difficulty newly set by the user, the characteristic information of the user, and the like, and then is sent to the client. And further, the dynamic adjustment of the pattern template of the answering question, the content resource of the question and the like is realized, so that different business requirements are met.

For example, to facilitate understanding of the interaction process between the client and the server in this embodiment, as shown in fig. 7, the following description of the system operation flow is given:

(a) after the teaching video is uploaded to the client side at the server side, a time node for triggering answering actions can be added to the teaching video;

(b) on the basis of (a), the server configures a topic template for each node, and adds specific topic contents;

(c) on the basis of (b), when the learner watches the video on the client side and reaches a preset time point, triggering an answering action, and displaying questions of the question and answer according to the specific configuration in the step 2;

(d) and (c) completing question answering by the learner, closing the question, and returning to continuously play the video.

This embodiment adds the mode of answer content in teaching video playing process, can effectually promote the user to the grasp of every knowledge point in the video.
